ECN Forum Forums Code Related Discussion NEC & other Code issues shunt trips for kitchen hood

Some FM's want the exhaust fans to remain on. If there is a fire up in the ducting, some of the Ansul will get sucked up in there. Also, it gets the smoke out of the kitchen.

Make Up fans/HVAC get shut down for sure, no need to keep feeding the fire with fresh oxygen, or suck it into the rest of the restaurant.
